Hail_The_loli

In the northern part of the world, a long-standing battle between various races and the demon race has finally reached its end. The Demon Lord, a figure with black hair, red eyes, rules from her obsidian palace, having repeatedly defeated the Goddess, the strongest being in the world. However, she refrains from killing her, knowing she will only be reborn to lead another attack.
As the goddess kneels before her, badly injured and helpless, the sounds of explosions echo outside, signaling the imminent victory of the alliance. Despite her immense power, the demon lord acknowledges the demon's overall weakness compared to humans and the Alliance. The development of fighting energy and mana has allowed ordinary humans to fight demons, leading to the demon army's defeat.
Aware of the Alliance's intent to enslave the abyssal demon, the Demon Lord decides to cast a forbidden spell that will cost her life. As the Alliance forces storm the palace, they hesitate upon sensing the spell's energy. The Demon Lord vows to resist and be reborn to save her people.
Meanwhile, the goddess reflects on the demon lord's past treatment of her and acknowledges her respect and dedication to her people. As the demon lord prepares to cast the spell, the goddess asks if she can abandon her plan and live freely. However, demon lords are duty-bound to restore the demon race's glory and protect her people.
Understanding the demon lord's resolve, the goddess readies her sword, intending to clash with the demo lord's forbidden spell. The resulting explosion creates a mushroom cloud, marking the end of the conflict and the start of a new era. The Demon Lord and the Goddess become historical figures, their stories occasionally told.

Abyssal Chronicles

The magical power, battle energy, holy power, soul power, and even shadow power between heaven and earth suddenly began to converge towards the central area of Anvika in an unimaginable state, and were rapidly absorbed into the ground in a spiral manner.

As for the location where this energy was gathering,

Below this location, was the absolute forbidden area of the Red Leaf Royal Family,

The place where the Demon Lord was sealed - the Underworld Palace.

As the most important secret place of the Red Leaf Royal Family, in order to avoid being detected, the Underworld Palace was built tens of thousands of meters underground below the palace. When constructing this underground palace, rare and hard materials far superior to the palace walls were used. Coupled with the remnants of the Goddess's power in the past, the Underworld Palace was able to remain intact even when the entire surface city was destroyed.
